MAX31341C Real Time Clock

Analog Devices MAX31341C Real-Time Clock is a low-current time-keeping device that provides nanoamperes time-keeping current by extending battery life. The MAX31341C supports 6pF high-ESR crystals that broaden the pool of usable crystals for the devices. This device is accessed through an I²C serial interface. The MAX31341C real-time clock features one digital Schmitt trigger input and one programmable threshold analog input. This clock generates an interrupt output on a falling or rising edge of the digital input (D1), or when the analog input (A_IN) voltage crosses a programmed threshold in either direction.
